No. For putting POV-Ray on a CD *in general* you must obtain written
permission by the POV-Team. But the distribution license contains an
explicit exceptions for Open source Operating system distribution. See:
http://www.povray.org/distribution-license.html
2.1. In return for the Distributor agreeing to be bound by the terms of
this agreement, POV grants the Distributor permission to make a
copy of the Software by including the Software in a generally
recognised Distribution of a recognised operating system where the
kernel of that operating system is made available under licensing
terms:
(a) which are approved by the Open Source Initiative
(www.opensource.org) as complying with the "Open Source
Definition" put forward by the Open Source Initiative; or
(b) which comply with the "free software definition" of the Free
Software Foundation (www.fsf.org).
2.2. As at June 2004, and without limiting the generality of the term,
each of the following is a "generally recognised Distribution" for
the purposes of clause 2.1: Debian, Red Hat (Enterprise and
Fedora), SuSE, Mandrake, Xandros, Gentoo and Knoppix Linux
distributions, and officially authorized distributions of the
FreeBSD, OpenBSD, and NetBSD projects.
It even mentions Knoppix explicitly!
Note this includes any commercial distribution (as long as the Kernel
complies with 2.1.a ot 2.1.b. This means that a Knoppix distribution
containing POV-Ray could be sold, bundled with books/magazines/whatever
without first obtaining permission.
I agree this is difficult to conclude from the license text but that's
because of the well known fact that the license has been originally
written when such things as Linux distributions did not exist and it had
to be adapted without breaking the spirit of the original license (which
has a strong emphasis on preventing to obscure the fact that POV-Ray can
be used for free).
